What’s the correct technique for finishing Mokume-Gane?

Mokume is very easy to work with. Even if you don’t like your surface finish, it’s simple to start over without ruining your finished product. We recommend using a 400-600 grit grind belt for a final finish, though you can choose to go higher. For a mirror-shiny finish, use a soft buffing compound after grinding. You can also buff out any scratches later. Over time, the copper, brass, and nickel silver in your Mokume begin to oxidize and turn dark. If you want to get this look faster, soak your Mokume in a patina solution. Some people also choose to soak their piece for 1 to 2 minutes in ferric chloride mixed with distilled water, then neutralize the acid with a dip in a baking soda/distilled water bath for 3 minutes. When you remove your Mokume from the baking soda, simply wash it off with water and a clean rag.
